5.5.3 Test Setup
5.5.4 Test Procedure Summary
The requirements of IEC 61000-4-2:2008 call out an Electrostatic Discharge (ESD) test level and procedure. The intent of this test is to determine the effect of electrostatic discharge events on equipment operation. ESD is the result of potential build-up and the subsequent rapid discharge and equalization of that potential. The result of the discharge is a transient waveform that produces peak voltages up to tens of kilovolts, peak currents of a few amperes, and rise times on the order of a few nanoseconds (ns). This discharge may produce malfunction and damage to sensitive electronic equipment.
Table-top EUTs are placed on a Horizontal Coupling Plane (HCP) and isolated from it by 0.5mm. The HCP was connected to a Ground Reference Plane (GRP) via a bonding strap with 470k-ohm resistors located at each end. When the Vertical Coupling Plane (VCP) was used, it was also connected to the GRP with a second bonding strap with 470k-ohm resistors located at each end.
EverPro Technologies Company Ltd. USB3.0 AOC Cable
The VCP is located 10 cm from the EUT for test. The earth cable of the ESD generator was attached to the GRP.
Contact discharge points were metallic points on the EUT that are subject to contact by operators or maintenance personnel. Air discharge points were non-conductive surfaces, indicators, and other points subject to contact.
The voltage was stepped at 1 kV, 2 kV, 4 kV for contact discharge and 2 kV, 4 kV, 8 kV for air discharges. The ESD simulator was then set at the test voltage and applied 10 times (positive and negative) at intervals of one second at each discharge test point. Two ESD modes were applied: direct application of the discharge to the EUT, and indirect application of the discharge to the horizontal and vertical coupling planes. Direct application simulates a static discharge to the EUT itself and indirect application simulates a static discharge to objects placed or installed near the EUT.
During test the system was monitored for performance degradation. Environmental Conditions during Electrostatic Discharge Testing

5.9.4 Test Procedure Summary
Let the EUT work in test mode and test it.
The EUT are placed on an insulating support 0.1m high above a ground reference plane. CDN (coupling and decoupling device) is placed on the ground plane about 0.3m from EUT. Cables between CDN and EUT are as short as possible, and their height above the ground reference plane shall be between 10 and 30 mm (where possible).
The disturbance signal described below is injected to EUT through CDN. The EUT operates within its operational mode(s) under intended climatic conditions after power on. The frequency range is swept from 0.150MHz to 80MHz using 3V signal level, and with the disturbance signal

According to the European EMC Directive (2004/108/EC), the conformity of a device to the Directive shall be certified by an EC declaration of conformity issued by the manufacturer or his authorized representative established within the European Community. If neither the manufacturer nor his authorized representative is established in the European Community, the EC declaration of conformity shall be the responsibility of the person who places the device on the European Community market.
The EC declaration of conformity shall be held at the disposal of the competent authority for ten years following the last placement of the device on the market (i.e., 10 years after that last device has been sold) and must contain the following information:
- Description of the device to which the declaration refers,
- Reference to the specifications under which conformity is declared, and, where appropriate, the national measures implemented to ensure the conformity of the provisions of the Directive,
- Identification of the signatory empowered to bind the manufacturer or his authorized representative.
An example of an EC declaration of conformity is shown on the next page.
Please note that Metrology and Test Center of Radio and TV, Academy of Broadcasting Planning operates as a contract-testing laboratory and provides test results to support the EC declaration of conformity. However, under the EC's current regulations, it is up to the manufacturer/importer to declare conformity to the proper standards. Although WLL can provide technical guidance, the final determinations as to which standards apply to the product and whether the product conforms to the standards is the responsibility of the manufacturer/importer.

D. Measurement Uncertainty
All results reported herein relate only to the equipment tested. The basis for uncertainty calculation uses ANSI/NCSL Z540-2-1997 with a type B evaluation of the standard uncertainty. Elements contributing to the standard uncertainty are combined using the method described in Equation 1 to arrive at the total standard uncertainty. The standard uncertainty is multiplied by the coverage factor to determine the expanded uncertainty which is generally accepted for use in
EverPro Technologies Company Ltd. USB3.0 AOC Cable
commercial, industrial, and regulatory applications and when health and safety are concerned (see Equation1 and Equation 2). A coverage factor was selected to yield a 95% confidence in the uncertainty estimation.
